The growing challenges of reducing exhaust emissions and improved fuel economy has triggered automotive engineers to design manufacture engine parts with superior mechanical properties dimensional accuracies. Valve guides are cylindrical structures supporting inlet valve stems during operation. Conventionally made grey cast iron material, guide suffers from severe wear losses leading loss increased due improper stem seating. Here, the synthesis a novel ferrous powder metallurgy composite is presented characteristics have been studied at varying loads 30 N, 40 N 50 sliding speeds 0.5 m/s, 1 m/s 2 under lubricated conditions. samples undergone nitriding heat treatment 1150 °C improve surface hardness 700 Hv. shown negative rates high capillary action lubricating oil exhibited stable friction coefficient values. This attributed formation hard phases Fe2N, Fe3N, Fe4N Fe(Mn)3C twinning-induced plastic compounds like (Fe24Mn) 0.08 as evident XRD analysis. morphological analysis worn out was done SEM Coupled EDS it showed micro-cutting, Ploughing, delamination main phenomenon.

Abstract Friction stir processing (FSP) is a well-known method for improving metal alloys’ surfaces by producing surface composites with better mechanical properties. This study examines how the tool tilt angle affects FSP region generation in an AZ31 magnesium (Mg) alloy reinforced yttria-stabilized zirconia (YSZ) and alumina (Al 2 O 3 ). The effect of different angles (T TA ) on dispersion, integration, distribution YSZ Al Mg matrix was investigated. Optical microscopy, scanning electron microscopy (SEM), Vickers hardness testing were used to extensively evaluate microstructural characteristics FSP-treated region. findings show that T has major impact composite’s homogeneity uniformity, 2° encouraging best possible dispersion YSZ/Al enhanced friction stirred hybrid composite (FSSHC) exhibits greater 137 HV as compared (106 HV) base (73 HV). due Orowan strengthening mechanism also because FSSHC ability withstand load through inclusion particles, homogeneous particles among recrystallized grains provides reinforcement across
